Canon G12 vs Pentax 645Z
The Canon PowerShot G12 and the Pentax 645Z are two digital cameras that were officially introduced, respectively, in September 2010 and April 2014. The G12 is a fixed lens compact, while the 645Z is a DSLR. The cameras are based on a 1/1.7-inch (G12) and a medium format (645Z) sensor. The Canon has a resolution of 10 megapixels, whereas the Pentax provides 51.1 MP.
Below is an overview of the main specs of the two cameras as a starting point for the comparison.
Going beyond this snapshot of core features and characteristics, what are the differences between the Canon PowerShot G12 and the Pentax 645Z? Which one should you buy? Read on to find out how these two cameras compare with respect to their body size, their imaging sensors, their shooting features, their input-output connections, and their reception by expert reviewers.
Body comparison
The side-by-side display below illustrates the physical size and weight of the Canon G12 and the Pentax 645Z. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All width, height and depth measures are rounded to the nearest millimeter.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Pentax 645Z is considerably larger (114 percent) than the Canon G12. It is noteworthy in this context that the 645Z is splash and dust-proof, while the G12 does not feature any corresponding weather-sealing.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the G12 has a lens built in, whereas the 645Z is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup.
Concerning battery life, the G12 gets 370 shots out of its Canon NB-7L battery, while the 645Z can take 650 images on a single charge of its Pentax D-LI90 power pack.
The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. If you would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

Any camera decision will obviously take relative prices into account. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The G12 was launched at a lower price than the 645Z, despite having a lens built in. Usually, retail prices stay at first close to the launch price, but after several months, discounts become available. Later in the product cycle and, in particular, when the replacement model is about to appear, further discounting and stock clearance sales often push the camera price considerably down. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.
Sensor comparison
The imaging sensor is at the core of digital cameras and its size is one of the main determining factors of image quality. A large sensor will generally have larger individual pixels that offer better low-light sensitivity, provide wider dynamic range, and have richer color-depth than smaller pixels in a sensor of the same technological generation. Further, a large sensor camera will give the photographer additional creative options when using shallow depth-of-field to isolate a subject from its background. On the downside, larger sensors tend to be associated with larger, more expensive camera bodies and lenses.
Of the two cameras under consideration, the Canon G12 features a 1/1.7-inch sensor and the Pentax 645Z a medium format sensor. The sensor area in the 645Z is 3242 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 4.6 and 0.79. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3.
With 51.1MP, the 645Z offers a higher resolution than the G12 (10MP), but the 645Z nevertheless has larger individual pixels (pixel pitch of 5.30μm versus 2.07μm for the G12) due to its larger sensor. Moreover, the 645Z is a much more recent model (by 3 years and 7 months) than the G12, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units. Coming back to sensor resolution, it should be mentioned that the 645Z has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Pentax 645Z implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 645Z for good quality output (200 dots per inch) amounts to 41.3 x 31 inches or 104.9 x 78.6 cm, for very good quality (250 dpi) 33 x 24.8 inches or 83.9 x 62.9 cm, and for excellent quality (300 dpi) 27.5 x 20.6 inches or 69.9 x 52.4 cm. The corresponding values for the Canon G12 are 18.2 x 13.7 inches or 46.3 x 34.7 cm for good quality, 14.6 x 10.9 inches or 37.1 x 27.8 cm for very good quality, and 12.2 x 9.1 inches or 30.9 x 23.2 cm for excellent quality prints.
The Canon PowerShot G12 has a native sensitivity range from ISO 80 to ISO 3200, which can be extended to ISO 80-12800. The corresponding ISO settings for the Pentax 645Z are ISO 100 to ISO 204800 (no boost).
In terms of underlying technology, the G12 is build around a CCD sensor, while the 645Z uses a CMOS imager. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.
Consistent information on actual sensor performance is available from DXO Mark for many cameras. This service assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. Of the two cameras under consideration, the 645Z offers substantially better image quality than the G12 (overall score 54 points higher). The advantage is based on 5.6 bits higher color depth, 3.5 EV in additional dynamic range, and 4.8 stops in additional low light sensitivity. The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Many modern cameras cannot only take still pictures, but also record videos. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the 645Z provides a better video resolution than the G12. It can shoot movie footage at 1080/60i, while the Canon is limited to 720/24p.
Feature comparison
Apart from body and sensor, cameras can and do differ across a variety of features. The G12 and the 645Z are similar in the sense that both have an optical viewfinder. The latter is useful for getting a clear image for framing even in brightly lit environments.

One difference between the cameras concerns the presence of an on-board flash. The G12 has one, while the 645Z does not. While the built-in flash of the G12 is not very powerful, it can at times be useful as a fill-in light.
The Pentax 645Z has an intervalometer built-in. This enables the photographer to capture time lapse sequences, such as flower blooming, a sunset or moon rise, without purchasing an external camera trigger and related software.
Concerning the storage of imaging data, both the G12 and the 645Z write their files to SDXC cards. The 645Z features dual card slots, which can be very useful in case a memory card fails. In contrast, the G12 only has one slot. The 645Z supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the G12 cannot take advantage of Ultra High Speed SD cards.
Connectivity comparison
For some imaging applications, the extent to which a camera can communicate with its environment can be an important aspect in the camera decision process. The table below provides an overview of the connectivity of the Canon PowerShot G12 and Pentax 645Z and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the 645Z has a microphone port, which can help to improve the quality of audio recordings by attaching an external microphone. The G12 does not feature such a mic input.
Studio photographers will appreciate that the Pentax 645Z (unlike the G12) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Both the G12 and the 645Z have been discontinued, but can regularly be found used on ebay. The G12 was replaced by the Canon G15, while the 645Z does not have a direct successor. Further information on the features and operation of the G12 and 645Z can be found, respectively, in the Canon G12 Manual (free pdf) or the online Pentax 645Z Manual.
Review summary
So how do things add up? Is there a clear favorite between the Canon G12 and the Pentax 645Z? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.
Reasons to prefer the Canon PowerShot G12:
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
- More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
- Ready to shoot: Comes with a built-in lens, while the 645Z requires a separate lens.
- More compact: Is smaller (112x76mm vs 156x117mm) and thus needs less room in the bag.
- Less heavy: Is lighter even though it comes with a built-in lens (unlike the 645Z).
- Sharper images: Has hand-shake reducing image stabilization built-in.
- Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
- More affordable: Was introduced at a lower price, despite coming with a built-in lens.
- More heavily discounted: Has been available for much longer (launched in September 2010).
Advantages of the Pentax 645Z:
- More detail: Has more megapixels (51.1 vs 10MP), which boosts linear resolution by 126%.
- Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
- Better image quality: Scores substantially higher (54 points) in the DXO overall evaluation.
- Richer colors: Generates noticeably more natural colors (5.6 bits more color depth).
- More dynamic range: Captures a broader range of light and dark details (3.5 EV of extra DR).
- Better low-light sensitivity: Can shoot in dim conditions (4.8 stops ISO advantage).
- Better video: Provides higher definition movie capture (1080/60i vs 720/24p).
- Better sound: Can connect to an external microphone for higher quality sound recording.
- Easier setting verification: Features a control panel on top to check shooting parameters.
- Larger screen: Has a bigger rear LCD (3.2" vs 2.8") for image review and settings control.
- More detailed LCD: Has a higher resolution rear screen (1037k vs 461k dots).
- Faster burst: Shoots at higher frequency (3 vs 1.1 flaps/sec) to capture the decisive moment.
- Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
- More flexible: Makes it possible to change lenses and thus to use specialty optics.
- Longer lasting: Gets more shots (650 versus 370) out of a single battery charge.
- Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
- Faster data transfer: Supports a more advanced USB protocol (3.0 vs 2.0).
- Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
- Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
- Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
- More modern: Reflects 3 years and 7 months of technical progress since the G12 launch.
If the number of relative strengths (bullet points above) is taken as a guide, the 645Z is the clear winner of the contest (21 : 9 points). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points when reflecting and deciding on a new camera. A professional wedding photographer will view the differences between cameras in a way that diverges from the perspective of a travel photog, and a person interested in cityscapes has distinct needs from a macro shooter. Hence, the decision which camera is best and worth buying is often a very personal one.
How about other alternatives? Do the specifications of the Canon G12 and the Pentax 645Z place the cameras among the top in their class? Find out in the latest Best Travel-Zoom Camera and Best DSLR Camera listings whether the two cameras rank among the cream of the crop.
In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains incomplete and does no justice, for example, to the way the G12 or the 645Z perform in practice. User reviews that are available, for instance, at amazon can sometimes shed light on these issues, but such feedback is all too often partial, inconsistent, and inaccurate.
Expert reviews
This is where reviews by experts come in. The following table reports the overall ratings of the cameras as published by some of the major camera review sites (amateurphotographer [AP], cameralabs [CL], digitalcameraworld [DCW], dpreview [DPR], ephotozine [EPZ], photographyblog [PB]). As can be seen, the professional reviewers agree in many cases on the quality of different cameras, but sometimes their assessments diverge, reinforcing the earlier point that a camera decision is often a very personal choice.

Care should be taken when interpreting the review scores above, though. The assessments were made in relation to similar cameras of the same technological generation. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
